Title: Book copying apparatus
Inventor: KOUMURA NOBORU
IPC: G03G21/00
Filed: 1982-12-17
Abstract: Image recording apparatus is capable of recording images of two side-by-side pages of a book-type original on front and back sides of different record papers. An image data of a first page of the two opened pages of the book-type original read by a first reading unit is supplied to a recording unit, and an image data of a second page of the original read by a second read unit is stored in a memory 203. The recording unit 80, 81 records on a single record sheet images based on the first image data and a third image data which was read and stored in the memory in a previous cycle. Hence the pages are reproduced in the same format as the book. Alternatively, the images of side-by-side pages may be recorded on the front and back of a single record sheet so that no storage is required but the format of the book is not retained. 
<??>Different ejection trays may be provided for different recording modes, and a book support having mutually inclined faces is described.

Title: A system for echo cancelling
Inventor: PHRYDAS CHRISTOPHER
IPC: H04B3/23
Filed: 1983-09-14
Abstract: In an echo canceller, e.g. for a QAM modem, the input to a synthesiser for the echo cancelling signal is produced by a coder having substantially the same frequency spectrum as a system employing a multiplying modulator. The coder 3 processes data elements ak and bk of a complex signal to produce an in-phase channel Ik and a quadrature channel Qk, which are applied respectively to an in-phase interpolating digital filter 4 and a quadrature interpolating digital filter 5, wherein each element is individually weighted. After passing through filters, 4 and 5, signal 6, which is a combination of output signals from filters 4 and 5, is applied to a combiner 7, wherein an error signal 9 is generated, signal 9 being the difference between signal 6 and an echo signal 8 which is required to be cancelled. Error signal 9 is applied to filters, 4 and 5, to be used to re-weight the elements, so as to reduce iteratively the error signal to a satisfactory minimum value. <IMAGE>

Filed: 1985-05-31
Abstract: A spray head assembly is made from a very few number of injection molded parts. Preferably a pair of elongated housing shells fit together in face-to-face confrontation, with a spring biased actuator arm or control lever pivotally mounted between them. The lever has a metal shaft extending therefrom, which passes through a flexible cone in a rubber bulkhead to maintain a waterproof seal. In front of the bulkhead is a solid plastic plate having mounted therein a reciprocally slidable member controlled by the lever. In one embodiment, the sliding member contains a generally triangular or circular opening or openings having a sector of a circle for a base. Depending upon the position of the slide, the opening moves up or down to open or close a water passageway through the spray head.
